E-64d in Cell-Death Screens: Read Death, Not Growth
2026-09-25
E-64d is a membrane-permeable cysteine protease inhibitor, but its effects in cell-death experiments are easiest to interpret when growth and death are measured separately. This article connects E-64d perturbation design to a time-resolved functional-genomics framework, clarifying what inhibitor responses can—and cannot—show.

Tin Mesoporphyrin IX as a Causal HO Probe
2026-09-25
Tin Mesoporphyrin IX (chloride) offers a way to test whether heme oxygenase activity contributes to redox-sensitive phenotypes, rather than merely tracking with them. This article connects its biochemical profile to practical assay choices in HBV and metabolic disease research while defining the limits of pharmacological inference.

Kozak Libraries Quantify Transgene Expression Effects
2026-09-24
Shukla and colleagues use a pooled Kozak sequence library to tune transgene abundance across an approximately 100-fold range, connecting sequence context to protein levels and cellular phenotypes. Their approach offers a heritable, library-compatible way to study how protein abundance interacts with coding variation, illustrated with ACE2-mediated viral entry and ACE2 and STIM1 variant panels.

DOPE for mRNA LNP Design and Endosomal Escape
2026-09-24
Learn how to use DOPE as a helper phospholipid when optimizing nucleic acid delivery, from stock preparation to cell-based readouts. A recent zwitterionic-lipid study offers a useful design lesson for improving endosomal escape—but DOPE and the study’s MeDZ lipid are not interchangeable.

Spiroplasma Entry into Drosophila S2 Cells
2026-09-23
Wei and colleagues established a Drosophila Schneider 2 cell model showing that Spiroplasma eriocheiris can invade, proliferate within, and damage insect-derived cells. Pharmacological and cytoskeletal perturbations implicated clathrin-mediated endocytosis, macropinocytosis, actin, myosin II, and microtubules, providing a mechanistic framework for studying a crustacean pathogen in an invertebrate cell system.

DDI2–NFE2L1 Signaling Protects From Ferroptosis
2026-09-21
The reference study identifies DDI2-mediated activation of NFE2L1 as an adaptive proteostasis circuit that limits ferroptosis after oxidative and lipid stress. Its combination of ubiquitylation-site proteomics, genetic perturbation, and pharmacological validation provides a framework for studying how proteasome remodeling influences ferroptotic vulnerability.

Bazedoxifene Repurposed as an Antimalarial
2026-09-20
The reference study shows that bazedoxifene, a third-generation selective estrogen receptor modulator, inhibits erythrocytic Plasmodium falciparum growth and reduces Plasmodium berghei infection in mice. Its strongest activity occurred against early ring-stage parasites and was associated with impaired hemozoin formation, supporting drug repurposing while highlighting important sex-specific and translational limitations.

NAT1–ENO1–Lactate Signaling in Colorectal Cancer
2026-09-19
A 2026 MedComm study defines a NAT1–ENO1–lactate pathway that connects tumor metabolism with TRAF6-dependent PD-L1 stabilization and immune escape in colorectal cancer. Its integrated database, multi-omics, cellular, patient, and mouse-model evidence provides a mechanistic framework for interpreting how lactate-pathway perturbation may influence checkpoint immunotherapy.

TMEM16F, Ferroptosis, and Tumor Immune Rejection
2026-09-19
Yang et al. identify TMEM16F-mediated plasma-membrane lipid scrambling as a late-stage suppressor of ferroptosis, showing that phospholipid redistribution can limit membrane collapse after lipid peroxide accumulation. Disrupting this response increases tumor vulnerability and strengthens PD-1 blockade, linking membrane biophysics with antitumor immunity.

Agatoxin-IVA Channels in Cardiac Vagal Neurons
2026-09-18
Wang, Irnaten, and Mendelowitz used whole-cell patch-clamp recordings to show that agatoxin-IVA-sensitive voltage-dependent calcium channels contribute to both presynaptic and postsynaptic nicotinic activation of cardiac vagal neurons. Their antagonist comparison separated this pathway from N- and Q-type channels and suggested an additional, selective role for L-type channels in glutamatergic synaptic facilitation.
